can we change QPixmap image of Qgraphicsscene dynamically?

can we change QPixmap image of Qgraphicsscene dynamically or at runtime ?

I have included timer ,and need to change image of scene as the timer gives signal timeout().

When you add the pixmap item for the first time using QGraphicsScene::addPixmap save the pointer to QGraphicsPixmpaItem returned by the function. Then, everytime the timeout signal is emitted using QGraphicsPixmapItem::setPixmap change the pixmap.

Hope this helps.

1 another query.

I have added QGraphicsview in Vertical Layout to view an image.

Now I want to rotate this image as well as move it vertically up and down.

I am able to rotate it using code

matrix.rotate(i);

ui.BGgraphicsView->setMatrix(matrix);

ui.BGgraphicsView->setMatrix(matrix);

To copy to clipboard, switch view to plain text mode 

but not able to move it up and down

I use below code for translating

matrix.translate(50,50);
ui.BGgraphicsView->setMatrix(matrix);

matrix.translate(50,50);
ui.BGgraphicsView->setMatrix(matrix);

To copy to clipboard, switch view to plain text mode 

Please help

SetPixmap does removes the current image from pixmap but not displaying the new pixmap image instead white empty Graphicsview is seen .
